Attack 20 on an m 1000

[HANDSOME]

My son replaced the challenger track with an attack 20 and the track clips and drive lugs are rubbing the diamond drive. Driver external teeth are centered in the track. Bearings are good. Track is tight. What could I be missing.

if i remember right the out side lugs on the drive side need to be trimmed down to clear the drive.

If you look at the outer lugs on the challenger you'll notice they are smaller. I believe they also turned the track clips around so the guides are on the inside of the track window.
